Definitions

  • the invention relates to a clutch disc for - both dry or wet running - friction clutches, such as those used in motor vehicles between the engine and manual transmission as a speed converter or torque interrupter.
  • the friction linings are riveted to spiral springs, so-called spring cushions.
  • These spring cushions are in turn attached to the torsion damper or, if this is not provided, as is the case, for example, in the clutch disc for a friction clutch, which works with a so-called dual-mass flywheel, directly on a continuous disc.
  • Torsion damper as well as the continuous disc are then, as already mentioned, in turn connected to the clutch disc hub, which is on the multi-spline profile of the
  • Gear input shaft slidably slides.
  • the invention has for its object to provide a clutch disc for a switchable friction clutch, in which the axial displacement profiles are structurally as close as possible in the vicinity of the friction radius of the clutch linings, and thereby the axial displacement is associated with minimal frictional loss, so that it actually clutch torque to be transmitted equals the calculated one.
  • This object is achieved with a clutch disc construction which has the features of claim 1. Advantageous refinements and developments of this clutch disc construction are the subject of the dependent claims.
  • the clutch disc according to the invention is divided into two parts. It consists of a base body which is axially detachably fixed on the gear shaft, for example with a spring-loaded ball which engages in a circumferential groove of the hub. This base body is not moved when disengaging or engaging. Are on this main body
  • Pad pairs or pad carriers with bonded pads for example in the form of a locking tab covering or in the form of a clamping sleeve covering or clamping clip covering. Only these are moved axially when the clutch is actuated. This significantly reduces the mass to be moved.
  • the pair of friction linings or friction lining carrier pair equipped with locking tabs is preferably designed in such a way that the intermediate clutch lining springs are slightly pretensioned when the linings or the lining carriers are locked. This ensures that the covering or covering carrier unit, when locked, can be ground on both sides and can be received and transported as a unit until it is installed in the clutch unit.
  • the clutch lining springs are, for example, elastic strands or hoses made of temperature-stable plastic, such as, for example, silicone or metallic bending leaf or torsion springs. So-called asymmetrical spring cushions can also be used without these having a negative effect on the so-called bursting strength of the mating unit.
  • the friction lining carriers are expediently made of light metal or plastic, in order to secure them to keep moving mass and its axial moment of inertia as small as possible.
  • the friction linings with locking tabs or the friction lining carriers with locking tabs, to which the friction linings are glued, are preferably constructed in such a way that these parts mutually lock themselves. In practical operation, the lock cannot be released, since this is prevented by the sliding webs on the clutch disc base.
  • the clutch linings can also be designed so that the lining springs are not loaded by any torque in order to optimize their material and function.
  • the clutch disc according to the invention for switchable friction clutches is particularly suitable for use in clutches with low lift-off or clearance, ie. H. in so-called low-lift couplings, because the locking minimizes distortion of the pairing unit.
  • this construction allows the tight thickness tolerances and low unbalances that are technically impossible to achieve with conventional clutch discs.
  • Friction materials no expensive reinforcement components such as yarns, wires, etc. If the brake pads are made of light metal, they are almost independent of temperature
  • the clutch disc according to the invention allows for a quick change of linings, since only the pair of friction linings locked or the pair of linings carriers locked with pads need to be exchanged.
  • the use of brake pads with pads is also very interesting from the point of recyclability.
  • the carriers can always be re-glued with friction linings.
  • the brake pads therefore do not have to be disposed of.
  • ring-shaped carriers for friction linings or also complete friction linings in the form of the carriers are proposed for both dry and wet clutches, which are axially displaceable and can be locked together.
  • FIG. 1 is a diagrammatic exploded view of the clutch disc according to a first embodiment, the two parts which are connected to one another in a rotationally fixed manner during operation but are axially displaceable relative to one another are shown separately,
  • FIG. 2 shows a part of the carrier for friction linings according to line II-II from FIG. 1 on an enlarged scale compared to FIG. 1,
  • FIG. 3 is a diagrammatic exploded view of the clutch disc according to a second embodiment
  • Fig. 4 is a perspective view of an embodiment for a clamping sleeve and a clamping clip for the clutch disc according to Fig. 3 and
  • FIG. 5 shows a perspective view of a second embodiment of a clamping clip and a clamping sleeve for the clutch disc according to FIG. 3.
  • the clutch disc 1 shown in FIGS. 1 and 2 consists essentially of two parts arranged coaxially to one another and displaceable relative to one another in the direction of an axis 2, which are described in more detail below.
  • the part of the clutch disc 1 which forms the base body 7 has a hub 3 with internal toothing 4, which on a shaft 5 leading to a gear (not shown) with corresponding external toothing 6 is locked in rotation and axially by a latching mechanism, for example by a shaft 5 spring-mounted ball 19 and a groove 20 arranged in the hub 3 is arranged.
  • a torsion damper 7a containing compression springs 8 is attached to the hub 3.
  • the torsion damper 7a has a disc 9 which is provided on the outer circumference with radially upstanding tongues 10 which serve as anchoring and displacement element for a friction lining carrier 11 which forms the second part of the clutch disc 1 and which is described in detail below.
  • the friction lining carrier 11 shown in the drawing consists of two ring disks 12 and 13, which are identical in their design and are arranged in mirror image to one another. These annular disks 12 and 13 are provided on the outer circumference and on the inner circumference with hook-shaped locking elements 14 which engage by relative rotation of the superimposed annular disks 12 and 13, which can be seen in particular in FIG. 1.
  • the washers 12 and 13 contain recesses 15 in the inner circumference, which are aligned with one another in the assembly position shown in FIG. 1, so that the assembled friction lining carrier 11 can be pushed onto the grand body 7, the
  • Tongues 10 of the disc 9 of the torsion damper 7a fit into the recesses 15 of the friction lining carrier 11 with a sliding or sliding seat, so that the friction lining carrier 11 can be displaced relative to the base body 7 during operation when the clutch is released and when the clutch is engaged, and the base body 7 with the hub 3 always remains in its mounting position on the shaft 5. Since the tongues 10 have a thickness which is sufficient so that when the friction lining carrier 11 is axially displaced during operation, both annular disks 12 and 13 always remain in the area of the tongues 10, during operation there is no fear of the annular disks rotating relative to one another and thus of unlocking, not possible there.
  • hoses 16 made of silicone rubber are inserted into the annular depressions 17 provided there, which, as shown by way of example in FIG. 2, have a rectangular or square, that is to say also circular or oval, cross section, while the
  • Hoses 16 are circular in cross section.
  • the spring cross-section can be positively influenced by the different cross-sectional shape of the ring groove and hose.
  • the spring identification can also be changed or adapted to the desired setpoint if, for example, the laying grooves are not centric circular grooves, but instead are carried out by a different groove distribution, for example a sinusoidal groove distribution.
  • a friction lining layer 18 is glued to the outside of the annular discs 12 and 13.
  • the ring disk 12 or 13 preferably consists of
  • clamping clips 22 which are resiliently clamped between the dovetail lugs on the outer circumference of the clutch lining pair or the clutch lining carrier pair, these two are Ring discs, between which the so-called pad suspension is then seated, clamped together or prevented from separating in the axial direction.
  • the so-called clamping sleeves 21 do the same on the inner zone of the pairing, in that the sleeves 21 are placed over the guide webs which cause the pair of pads or carrier pair to slide on the base body 25. In principle, however, attaching the clamping sleeves or clamping clips in a different form is also conceivable.
  • a pair of friction linings or, in the case of glued-on linings, can be used directly on the pair of lining carriers.
